THOMASJ. SHEEHAN, OF:ST. LOU-IS, MISSOURI;

REFRIGERATING- APPARATUS.

' all whom it'mdy concern: J

Be it' known that I, THOMAS J SHEEHAN, a citizen of'the United States,residing at r 'St. Louis, in the State of Missouri, have in.-

vented certain new and useful Improve-- ments in RefrigeratingApparatus,of which the following is a specification.

Water at atmospheric temperature or at a temperature of Water in watermains is in warm weather notsatisfying to quench the thirst, while icewater (by which is meant water derived from the melting of ice or waterthat has come into immediate contact with ice) I is. detrimentalto thehealth, be-

cause of beingintensely cold or on account of impurities in theice. Theobject of this invention is to supply Water that is indirectly cooledorrefrigerated and, more particularly, to provide apparatus for thispurpose that is suitable for installation in factories, for streetfountains, and in other 10- cations where considerable quantities ofrefrigerated waterwill be consumed.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur,

Figure. 1 is a front sectional elevation taken on the line l.l in Fig.3;

Fig, 2 is a side sectional elevation taken on the line 2-2,in Fig, 3;and

Fig. 3 is a section taken on the line 33 in Figs. 1 and 2, showing thehelical pipe coilk located in the bottom of-the storage tan The baselreceives the threaded tubular member 2, which at the opposite end isthreaded into the bottom part of support 3, thus forming a cast ironadjustable stand upon which the bed 4 for the metal tank 5 rests.

Within tank 5 is contained another tank 6 of smaller diameter andsomewhat less height, the space surrounding the said tank 6 and beneaththe same and between the wall of tank 6 and the wall of tank 5 andbetween the bottom of tank 6 and the bottom of tank 5 being filled withsuitable insulating material 7, such, for instance, as ground cork orthe like.

Thebed 4 is provided with flange 8 to keep tank. 5 from sliding off ofit, and also with depending flange 9 so as to keep it from sliding offof the flat top of the pedestal member 3.

6 containing the insulation 7 is closed by a fiat ring 10 havin thedepending beads 11 to grasp the top e ges of tanks 5 and 6 and confinethe same as well as hold the said ring 10 in place.-

The hole within ring 10 forms a mouth for-the tank or receptacle formedby the combination of tanks 5 and 6 and ring 1, as above described,which mouth is normally closed by lid or plate 12 formed with the flange13 that rests upon the gasket 14 (preferably made of rubber) which is soshaped as to have the upper flange 15 and lower flange 16 overlyin andunderlying respectively the flange 1T of ring 10. The lid 12 will beremoved, as a general rule, only when it is desired to insert a block orblocks of ice 18 or. tocleanse the interior of tank 6. The shape of thegasket 14 prevents its displacement when lid 12 is raised. The strainer19 prevents straw or the like passing through the drain pipe 20, butwater and smaller debris will drain out of tank 6 through drain 20whenever cock 21 is opened.

A storage tank 22 provided with a nor mally closed lid 23 is supportedby arms 24 from the inside of the wall of tank 6, and also more or lessby the water supply pipe 25 and the pipe 26 that carries refrigeratedwater from tank 22 to the enameled bubbling cup 27 containing the nozzle28.

The lower end of pipe 26 opens adjacent to the bottom of storage tank 22and adjacent to the cooling coil 29, thereby drawing off the cooledwater from storage tank 22.

The flow of water out of tank 22 through pipe 26 to fountain 27 takesplace whenever self-closing cock 30 is opened. Cock 30 is preferablylocated at the right hand of the drinking cup 27 so as to facilitate itsoperation by the majority of people. Any suitable drain 42 may beprovided from fountain 27 to carry ofl surplus water, the return ofwhich to tank 22 is prevented by the automatic closing of cock 30.

Pipe 25 connects with the water mains that furnish the supply of waterand the entrance of such supply is controlled by cook 31. Pipe 25 leadsto one end of the coiled pipe 29, the other end of which connects withpipe 32 having the outlets 33 and its extremity 34 terminating withinlid 23. The outlets 33 are within the storage tank 22 but near its top,so that the water most recently entered into tank 22 will be at the onthe inner perlphery top while that which has been in tank 22 longestwill be at the bottom, the inlet being, as just stated, at the top ofthe inside of tank 22 while the mouth of pipe 26 through which the Wateris drawn out of tank 22 is located near the bottom of tank 22. Thenatural tendency of cold water is to descend, due to its greater gravityas compared to warm water, and thus as the water near the top-of tank 22becomes chilled it gravitates toward the bottom of the said tank. By thearrangement that has been described whereby the water from the supplymain first enters tank 22adjacent to its bottom and is then forced topass through all the Winds of coil 29 and then to pass through pipe 32to the upper part of tank 22 the newly admitted water becomesconsiderably chilled before it is emitted through outlets 33 becausecoil 29 is located in the bottom of tank 22 where the water is thecoldest, and the newly admitted Water coming in through pipe 25 isobliged to travel a considerable distance through the said coil 29before the said water can reach pipe 32. 7

By this construction the maximum cooling effect from ice 18 is securedbecause the newly admitted water must spend considerable time in thecoldest partof tank 22 and then the same water is not immediately drawnout through pipe 26 but must continue the chilling process by beingemitted from pipe 32 only in the uppermost part of tank 22 where thechilling influence continues while it gradually sinks to the bot tom oftank 22.

The chilling influence of ice 18 upon the contents of tank 22 isenhanced by allowing the water to surround tank 22 which water willeither be initially introduced, as, for instance, by a bucket or willresult from the accumulations from melting ice, the ice 18 coming intocontact with the outside of tank 22.

To prevent the water within tank 6 accumulating to an undue extent, theoverflow outlet 35 is provided, which leads by pipe 36 to the bend 37atthe height of the maximum water line 38. WVhen the Water rises as highas the'water line 38 the water automatically Copies of this patent maybe obtained for five cents each, by addres Washington, D. 6.

begins to flow through outlet 35, pipe 36, pipe 39, to drain 20. Outlet35 is supported by one of the arms 24, cut short for this purpose.

When it desired to cleanse the interior of tank 22, cock 40 may beopened and the said tank allowed to drain into thertank 6, which in turndrains through strainer 19 into drain 20. r

The tank 6 is partially supported by pipes 35, 36, and 39 and'by pipe26, and is addi- V tionally supported by a plurality of feet 41.

Having thus described this invention, I

hereby reserve the benefit of all changes in form, arrangement, order,or use of parts, as 1t 18 evident that many mlnor'changes may be madetherein without departing from the spirit of this invention or followingclaim:

In a water cooling apparatuathe combination of a casing comprising innerand outer walls with interposed insulating ma terial therebetween, thecasing having an opening in the top, a cover fitted in the openthe scopeof the ing, a water receptacle in'the casing, said 7 receptacle beingspaced from the walls of the casing, a service pipe extending throughthe casing and into the receptacle, and coiled in the bottom of thelatter, the end of'the service pipe extending vertically from the centerof the coil and terminating in the top of the receptacle, a series ofshort outlet ice placed in the casing to insure the body of water in thetop part of the'receptacle being cooled.
